Revenge has PS2/Xbox and X360 runs in different categories. The same should be done here - load times are quicker on X360, and unless the time should be calculated without loads (which is tedious considering load times vary) then the same system used for Revenge should be used here.

Refer to my pastebin if you're unaware of this: https://pastebin.com/yLtqdySB

Edit: Just learnt that running it from disc on X360 is slightly slower too. god this is messy
